The enzyme propanediol dehydratase (EC 4.2.1.28) catalyzes the chemical reaction
- propane-1,2-diol propanal + H2O
This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is propane-1,2-diol hydro-lyase (propanal-forming). Other names in common use include meso-2,3-butanediol dehydrase, diol dehydratase, DL-1,2-propanediol hydro-lyase, diol dehydrase, adenosylcobalamin-dependent diol dehydratase, propanediol dehydrase, coenzyme B12-dependent diol dehydrase, 1,2-propanediol dehydratase, dioldehydratase, and propane-1,2-diol hydro-lyase. This enzyme participates in glycerolipid metabolism. It employs one cofactor, cobamide.
